AdoptOpenJDK HomeBrew Tap

AdoptOpenJDK - HomeBrew TAP

Usage

To always get the latest and greatest AdoptOpenJDK, run:

$ brew install --cask adoptopenjdk

The adoptopenjdk cask will automatically upgrade to the newest patch or major release as soon as it comes out.

To stay with a specific major release, activate the AdoptOpenJDK tap with brew tap and then install the desired version with brew install --cask <version>:

$ brew tap AdoptOpenJDK/openjdk
$ brew install --cask <version>

To install AdoptOpenJDK 14 with HotSpot, run:

$ brew tap AdoptOpenJDK/openjdk
$ brew install --cask adoptopenjdk14

Multiple major releases can be installed side-by-side. To get a list of available versions, run brew search adoptopenjdk or see the list here in the README.

* Large heap: Use this if you need heap memory > 57GB, or > 25GB on Linux. It enables -Xnocompressedref (doc). Use it along with -Xmx (doc) which sets the max heap size.

Switch between different JDK versions

1. Add the below function in your ~/.bashrc or ~/.zshrc

jdk() {
        version=$1
        export JAVA_HOME=$(/usr/libexec/java_home -v"$version");
        java -version
 }

For Fish shell user, add the below function in your ~/.config/fish/functions

function jdk
	set java_version $argv
	set -Ux JAVA_HOME (/usr/libexec/java_home -v $java_version)
	java -version
end

2. Source the profile and you can change the version like below:

 jdk 1.8
 jdk 9
 jdk 11
 jdk 13

Adding a new cask

If a new major version has been released (e.g 14) add it to casks.txt. Normally you just need to copy the list of casks from the previous major version. e.g

# OpenJDK14
adoptopenjdk14
adoptopenjdk14-jre
adoptopenjdk14-openj9
adoptopenjdk14-openj9-jre
adoptopenjdk14-openj9-large
adoptopenjdk14-openj9-jre-large
